® ®• Sound radiated from a “point source” has the most optimum stereo imagingbecause the separation of the acoustical centers between the midrange andtweeter for each channel is at the optimum. Figure 2-A describes ahorizontal speaker alignment. In a closed environment such as anautomobile, horizontal speaker alignment can cause severe amplitude andphase differences which will degrade not only the imaging, but also thefrequency response. This is due to the path length differences between themidrange and tweeter. Figure 2-B displays a vertical alignment between themidrange and tweeter. With a vertical alignment, the path length differencebetween the midrange and tweeter are reduced to a minimum. The resultis a negligible difference in path lengths between the midrange and tweeterregardless of the proximity of the listener to the speakers. Mounting thespeaker with minimum path length difference will ensure the best stagingand imaging possible from your audio system.INSTALLATIONMounting the MidrangeINSTALLATION1. Cut the proper size hole for the midrange/woofer.• For the FNQ1404, cut a 98.55mm (3 29 ⁄32") diameter hole• For the FNQ1405, cut a 115.57mm (4 9 ⁄16") diameter hole• For the FNQ1406, cut a 148.51mm (5 27 ⁄32") diameter hole2. Place the midrange over the mounting hole and mark the location of thescrew mounting holes.3. Remove the midrange. Drill the holes for the screws using a 1/8" drill bit.4. Route the wire through the hole.5. Attach the wires and be sure to observe the proper speaker polarity.6. Place the speaker into the hole and screw the speaker into place. Becareful not to bend the speaker frame during this step.7. Press the speaker grille into the mounting ring.– 7 –
